One fact while doing PISA measurement.
Must lower baseline 40 or lower cm/s. Cannot be used on multiple jet. ERO/ROA calculated by PISA. Valve should be completely closed in systole.

True/ False: Larger the Regurgitant Volume, Darker the envelope of MR flow.
True. Density is proportional to the number of blood cells within beam.
